The Lowdown
Alright, Rusty here again. Gotta be honest with you—this stretch at Kennebunk Beach is looking pretty grim for the next week and a half. If you’re looking for waves, you’re gonna be checking the cam a lot and seeing a whole lot of flat.
We’ve got a long gap from now all the way until Saturday the 12th. The first few days? Forget it. Tiny swell, next to no energy—the combined energy readings are way down in the weak zone, under 100. We’re talking 0.6ft to 0.9ft junk with short, choppy periods. Even when the wind swings offshore, the swell is just too small to do anything with.
The only day that even gets a mention is Sunday the 6th. We get a little bump to 1ft of ENE swell, with the combined energy hitting 171—moderate at best—and a short 7-second period. With the NNE breeze in the morning it’ll be clean. You might catch a crumbly one, but it’s nothing to write home about.
Now, mark your calendar for Saturday the 12th of September. That afternoon, we see a jump to 2ft of ENE swell and the combined energy hits 480—that’s a solid moderate push. The wind goes light and glassy, cross-offshore. That’s the best we get in the whole 16-day run. The waves will have some shape and the surface will be clean. Still, it’s a short-period swell at 7 seconds, so don't expect a long-period groundswell. It'll be the one day where a proper session is on the cards.
After that? Right back to flatness. By the 13th, the swell drops under 1.0ft and the energy tanks again. The water temp is about normal for this time of year. Into the second week, the swell gets longer period (12–13 seconds), but the wave heights are only 0.3ft to 0.6ft. That’s not surf, that’s a lake.
So here’s the bottom line: your only real shot is the afternoon of Saturday the 12th of September. The rest of the 16 days are a total wash. Painful for a surfer, but the forecast can always flip.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
